electronic warfare

The most commonly practiced types of electronic warfare are jamming, which falls under the category of
electronic countermeasures (ECM), and eavesdropping on enemy communications, which is known as signals intelligence (SIGINT) gathering. The purpose of jamming is to limit an enemy’s ability to exchange information by overriding radio transmissions or by sending signals to prevent radar...

...part of the U.S. and Soviet nuclear forces after their deployment in 1975, 1985, and 1988, respectively. In common with all first-line combat aircraft, they were equipped with sophisticated
electronic countermeasure (ECM) equipment designed to jam or deceive enemy radars. They could deliver free-fall conventional or nuclear bombs, air-to-surface missiles, and cruise missiles. The B-1B...

suppression of air defenses

...at the price of spoiling the mission. Air defenses had to be destroyed; in order to do this, aircraft had not only to outfly and outgun the weapons but also to foil their guidance mechanisms with
electronic countermeasures (ECM).

use of radar

The purpose of hostile
electronic countermeasures (ECM) is to degrade the effectiveness of military radar deliberately. ECM can consist of (1) noise jamming that enters the receiver via the antenna and increases the noise level at the input of the receiver, (2) false target generation, or repeater jamming, by which hostile jammers introduce additional signals into the radar receiver in an...
